APPARATUS FOR PUMPING GAS.

SPECIFICATION forming part of Letters Patent No. 505,973, dated October 3, 1893.

Application filed July 5, 1892. Serial No. 439,080. (No model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES W. BUERKLE and BERNARD A. BUERKLE, J r., citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Pumping Gas; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to an improved apparatus for pumping gas, and consists in certain details of construction, and combination of parts as will be fully described hereinafter.

In the accompanying drawings, Figure 1, is a side elevation of our improved apparatus for pumping gas, which is constructed in accordance with our invention. Fig. 2 is an enlarged sectional elevation of one of the cylinders. Fig. 3 is an enlarged detailed sectional elevation of one of the valves. Fig. 4 is an enlarged detailed sectional elevation of the other valve.

To construct an apparatus in accordance with our invention we provide two cylinders 1 of a suitable size, arranged side by side in a vertical position. These cylinders 1 are connected at their base by two pipes 5-6, each of which is provided with a valve 3 4, respectively and also with branch pipes 7-8 leading to an ordinary pumping apparatus 9. These valves 3--4 are somewhat similar in construction, and each consists of a shell having slide valves 15, connected together by a rod 10, and operated by means of a rolling or sliding weight 12. This weight 12, is confined in a shell 11, pivoted to the side of the valve casing by means of a short shaft 13. This shaft 13 is fitted with an arm 14, having a split end which operates between two collars formed on the valve stem 10. Each of these valves is provided with two seats whereby the direction of the liquid passing through the same may be changed. Fitted on the top of the cylinders 1 are caps 2, and intermediate plate 22, in which a check valve 24, is arranged. This valve 24 is balanced by means of a lever 27 pivoted to an arm 28, and weight 29, and when operated ou, is prevented fora time fromv closing by means of a sliding shoe 26. 4This sliding shoe 26, is operated by a float 20, resting on the top of a pivoted lever 21, and balanced by a counter Weight 25, in a manner such that when the said float is lifted from the lever the weight will move the piece beneath the valve 24, to prevent the same from closing, and when again placed on the lever will withdraw the said sliding piece and allow the valve to close. Entering the cylinders 1 are inlet pipes 30, each provided with check valves 23 to prevent back pressure, and each of the caps 2 has a valve 19 for the same purpose, and outlet pipes 18.

In operation, water is rst iilled in one of the cylinders l, and the valves set as shown in full lines in Fig. 3, and in dotted lines in Fig. 4. The pump 9, is started to remove the Water from the left hand cylinder to the right hand cylinder as the parts are seen in Fig. 1, and thereby force the gas contained in the last mentioned cylinder which gas has been previously admitted through the gas inlet pipe 30 under great pressure through the pipe 18 to points or places requiring its use. After the water has reached the float in the right hand cylinder said oat is lifted and the valve 24 held open by the engagement of the sliding shoe 26 with the under surface thereof, said shoe having been shifted by the turning of the lever 21 about its pivot after being freed from the float until the Water returns into the cylinder below, and the said ioat 20, moving upward closes the valve Vorifice 19, said ioat being guided in suitable guides 20a as clearly seen in Fig. 2. When this orifice has been closed the pressure becomes so great that the weight of the balls 12 is overcome by the back pressure agaimst the valves 15, so that the valves are moved to reverse their positions shifting the shells 11 and balls 12 to the position seen in full lines in Fig. 4 which will permit the Water to be pumped from the right hand cylinder to the left hand cylinder. This operation is continuous, forcing the water first into one cylinder, and then into the other, thereby forcing the gas entering the cylinders out of the exit pipe under great pressure.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

In an apparatus for pumping gas, the cornbination with two cylinders having partitions dividing eaeh cylinder into an upper and a lower compartment, valves iu said partitions, gas inlet and outlet pipes connecting respectively with lthe lower and upper compartmentsof the ey1inders,liquid inletpipes connecting the lower compartments of said cylinders with one another, Valves in said pipes, means for forcing the liquid from one of said cylinders through said liquid inlet pipes into the other cylinder, a tilting shell secured to each of the valves in the liquid inlet pipes, and a 15 shifting Weight in each of said shells, substantially as set forth. t

In testimony that we claim the foregoing We hereunto affix our signatures this Sth day of April, A. D. 18.92.
